Fitbit Integration Logging In but not Connecting

I am currently trying to connect my Fitbit account to Strava. I follow all the prompts from within the Strava app, login to my Fitbit account, but then, rather than granting permission, Strava simply displays the Fitbit webpage on the Strava app. It logs me in to Fitbit, but on a browser run through Strava. If I hit back, the log-in does not count as permissions.
